Expert Care for Artery and Vein Conditions 

Your vascular system is your body’s lifeline—delivering oxygen-rich blood to every organ and tissue. But when arteries or veins become narrowed, blocked, or weakened, it can threaten your mobility, comfort, and even your life.

At CLS Health, our vascular surgery team provides expert care for conditions that affect your arteries and veins. We treat everything from peripheral artery disease (PAD) and carotid artery disease to aortic aneurysms and deep vein thrombosis (DVT). Our Surgeons perform procedures in both outpatient and hospital settings to match the level of care you need.

Whether you’re managing a chronic condition or navigating new symptoms, we’re here to restore circulation, relieve discomfort, and reduce your risk of future complications—with a care plan that's just right for you.

What is included in a vascular screening? 

Vascular screening is a quick, painless, and non-invasive way to detect early signs of atherosclerosis—fatty buildup that can narrow or block your arteries. Left untreated, these blockages may increase your risk of stroke, heart attack, or limb loss.

  • Screenings may include imaging tests such as a carotid ultrasound, abdominal aortic aneurysm (AAA) screening, ankle-brachial index (ABI), or other blood flow studies. 
  • If results suggest an issue, our vascular surgeons work closely with your primary care provider to ensure you receive the right care at the right time so you can stay ahead of serious complications and protect your long-term health.

Conditions Treated

At CLS Health, we treat artery conditions that reduce healthy blood flow and increase the risk of stroke, tissue damage, or limb complications. This includes carotid and vertebral artery disease, peripheral artery disease (PAD), lower-extremity ischemic disease, and arterial blockages in the abdomen or legs. We also manage aortic conditions, including aneurysms and descending aortic disease, which can be serious if not monitored and treated early. Our goal is to restore circulation, prevent complications, and improve long-term vascular health. 

We care for vein disorders that affect circulation, comfort, and clot risk in the legs and pelvis. This includes deep vein thrombosis (DVT), varicose veins, chronic venous insufficiency, and May-Thurner syndrome, a condition that increases clot risk due to vein compression. Our treatments focus on improving blood return, reducing pain and swelling, and preventing long-term complications like ulcers or recurrent clots. We offer both conservative and advanced procedural options based on your needs. 

Some vascular conditions affect circulation in specific regions of the body, requiring highly specialized evaluation and care. We treat thoracic outlet syndrome, which can cause arm pain or circulation issues, as well as vascular conditions involving the kidneys and intestines, including renal and mesenteric artery disease. We also manage intestinal vascular disorders, which can impact digestion and organ health if left untreated. Our approach is personalized, precise, and designed to protect long-term function and quality of life. 

Treatments & Procedures 

At CLS Health, we offer advanced minimally invasive procedures to restore circulation with less pain, shorter recovery, and smaller incisions. We perform endovascular stenting and angioplasty to open blocked arteries, atherectomy to remove plaque, and carotid stenting to reduce stroke risk. We also treat varicose veins with radiofrequency ablation and repair aortic aneurysms using stent-based techniques like descending aorta stent placement. These image-guided approaches help improve blood flow while supporting faster healing. 

When surgery offers the safest or most effective outcome, our vascular specialists perform procedures to rebuild circulation and prevent serious complications. This includes carotid endarterectomy to prevent stroke, aortic aneurysm repair in the chest or abdomen, and lower-extremity bypass surgery to restore blood flow to the legs. We also perform arterial or venous thrombectomy to remove dangerous clots and preserve tissues. Each surgical plan is tailored to your unique anatomy and medical needs. 

We provide complex vascular solutions for patients with unique or advanced circulation needs. This includes renal and intestinal artery reconstruction, IVC filter placement or removal to protect lungs from clots, and dialysis access creation and repair for patients requiring long-term hemodialysis. Our goal is to improve long-term vessel health, maintain organ function, and support life-changing therapies when needed. 

Vein Center & Vascular MedSpa

At CLS Health, our Vein Center and Vascular MedSpa combines medical expertise with aesthetic precision to treat visible veins and skin concerns while improving overall circulation. Our team of board-certified vascular specialists performs every procedure, ensuring results that are both beautiful and medically sound. 

  • We offer safe, effective, and non-surgical treatments for spider veins, varicose veins, facial veins, and cosmetic discoloration—helping you look and feel more confident in your skin. 
  • Our cosmetic vascular treatments include sclerotherapy, laser vein reduction, and minimally invasive vein closure therapies, all designed for minimal discomfort and little to no downtime. 

Whether you’re seeking relief from aching, swollen veins or simply want smoother, clearer skin, we tailor every treatment to your individual goals. At CLS Health, you don’t have to choose between clinical care and cosmetic results—you receive both in one comprehensive experience.

FAQs

The most affected vessels include the: 

  • Carotid arteries – Located in the neck; they supply blood to the brain. 
  • Abdominal aorta – The main artery in the abdomen that can develop aneurysms. 
  • Femoral arteries – Found in the legs and commonly affected by peripheral artery disease (PAD). 

Other arteries throughout the body may also be affected. Vascular diseases often involve clogged arteries due to cholesterol buildup (atherosclerosis) or weakened arterial walls that can lead to aneurysms. These are the types of issues vascular surgery is designed to treat. 

Varicose veins are caused by weakened or damaged vein valves that allow blood to pool, often in the legs. Risk factors include genetics, prolonged standing, pregnancy, obesity, and aging. 

No. Spider veins are smaller, surface-level veins that appear red or blue and are usually cosmetic. Varicose veins are larger, bulging veins that may cause pain, swelling, or heaviness in the legs. 

PAD is a condition where narrowed arteries reduce blood flow to the limbs—usually the legs—causing symptoms like leg pain when walking, cold feet, or non-healing wounds. 

Treatments include compression therapy, sclerotherapy, radiofrequency ablation (RFA), endovenous laser therapy (EVLT), and vein stripping. Minimally invasive procedures are often performed in-office with little downtime. 

In many cases, vascular screening is covered if you have risk factors such as high blood pressure, diabetes, smoking history, or a family history of vascular disease. Coverage depends on your specific insurance plan. 

Warning signs include leg swelling, aching or cramping, skin discoloration, non-healing wounds, cold limbs, and bulging veins. Prompt evaluation is important to avoid complications. 

You should see a vascular specialist if you have persistent leg pain, visible veins, circulation problems, diabetic ulcers, or have been diagnosed with PAD or a blood clot. 

Yes. Exercise, weight loss, elevating the legs, and avoiding prolonged standing or sitting can help improve circulation and reduce symptoms of vein disease.
